Halogen free
Halogen free flame retardant (HFFR), low smoke zero halogen (LSOH), low smoke and fume (LSF) are all names associated with compounds that are used extensively in the cable, flooring and foam insulation.
These compounds are generally based on polyethylene or co-polymers of polyethylene with the addition of mineral fillers to impart flame retardant properties. They are finding increasing use as replacements for PVC and other halogenated polymers for applications where lower smoke and lower acid gas evolution are required during a fire situation. This could be in an underground or over ground railway, airport, ship, offshore rig or in any other public building or space.
HFFR compounds can be either thermoplastic or cross-linked, the latter are used where higher temperature ratings are required such as the insulation of cable conductors. This can also be applied to other applications where improved heat distortion temperature is required or high burst strengths such as in hot and cold water pipes. Crosslinking can also improve the crack resistance and the low temperature performance particularly for flexible applications.
We produce a wide range of HFFR materials which are designed to meet the requirements of the wire and cable, heatshrink and injection moulding industries. However, there are other industries where HFFR materials are, or will be, required.
We would be delighted to hear from companies who are not involved in our usual markets to investigate the possibility of introducing our technology into new product areas. If you are interested in halogen free materials please do not hesitate to contact us; we would be pleased to discuss whether one of our products will suit your needs. You may be involved in the electrical industry; manufacture building products such as wall panels and linings, pipe insulation, flooring, etc.
Presented here are a selection of our standard grades, but if none of these are suitable for your requirements then we would be delighted to consider the possibility of working with you to develop something special for your application. If you are interested in detailed information for the cable industry you may wish to explore through our Wire and Cable section.

Please note that all of the silane crosslinkable grades are shown as a system with a graft and a catalyst. These are normally used in the ratio of 95:5. The most common catalyst masterbatch is shown in the table but there are others available which helps us to more accurately match your property requirements and processing conditions.
Thermoplastic grades are available in natural, black and with additional UV stabilization.
